TROUGH FOR WET-SPINNING vMACHIN Application filed July 12,v 1927, serial No. 205,198, and infGermny' september-9, 1925.

In spinning flax by machines including a water trough, the roving is drawn through a trough filled with warm water at a temperature of about lO-700 C. for the purpose of loosening the long line or tow threads in order to render the threads suitable for drawing between the drawing rollers.

Timber was hitherto used in the construction of this hot water trough. Pine or larch wood posts of about 22 to 25 feet in length, and about 11 inches broad by about 16 inches thick were joined together to form a watertight vessel by grooved and tongued joints or by rabbeting vand screwing together with 15 strong wood screws and using red-lead cement as the jointing medium. The whole vessel was then waterproofed' with three coats of red lead and varnish. Any knot holes had to be previously bored out, stopped with wooden plugs and made watertight with varnish and -red lead cement. With the best selected timber, the very best care in making the trough, and a good red-lead varnish coating, these troughs would sometimes last 2O to 30 years. With careless construction, the life of thetrough was much shorter and often the troughs had to be repaired after a few years use, because the joints became leaky, knots rotted out, the plugs let in water, and resinous parts of the wood decayed.

The water dripping from the leaks naturally affected the durability, wear and elficiency of the s indle driving cords, apart from the fact that the loss of warm water should be avoided as far as possible for obvious reasons.

The present invention consists in constructing these long troughs of metal-reinforced concrete, making them in parts or sections which are joined together. Troughs or sections of a convenient length do not put too much strain on the resistance of the mass to bending and thus enable comparatively long troughs to be made, using for this purpose the aforesaid material which has already been used for various cluding troughs. n

The trough sections are joined at the ends by means of cast-iron coupling rings with project-ions and grooves which are secured in the concrete body by means of lugs cast thereon. The longitudinal reinforcements terminate in these rings. The joint is made tight preferably by inserting red lead cepurposes, in-

ment between the projections and grooves trough sections to be kept in readiness for rapidreplacement.

l he drawing'illustrates one constructional example. 1 Fig. lis'atransverse section through a metal-reinforced concrete trough according vto this invention.

Fig. 2 is a sectionl through theinner end of suchv a trough m'adevin` two halves.

nFig. 3 is a longitudinal section through the middle portion ofatWo-part trough, showing theparts slightly separated. The numeral 1 represents the roving which passes through thev tubek 2 and through the warm water ybath over the glass rod .3. Wrought iron'angle pieces 4 and' are embedded inthe concrete trough 19, and upon ythem'the brass bridge pieces `8 are fastened by means of "brass screws. .The 'sheet asbestos covers '9, andv 10 are strengthened by means of cast-iron bars 12 to Yprevent them from warping owing to the water tempera* turein the trough varying from about 100 Eto 7()O C. i The covers rest loosely upon the brass bridge pieces 8, but are kept in place in recesses formed by raised parts 18.

The longitudinal reinforcement at the vulnerable parts consists vof round iron 6 of about 1/1 inch diameter and at the other parts consists of strap iron The transverse reinforcement consists of flat iron strips, simi.- lar to the longitudinal reinforcement The glass rod 3 overwhich the thread is delivered, lis fixed in recesses by brass strips 11 at the rim Iof the trough.

At the jointsofgthe two halves of the trough, the brass strips are somewhat wider in order to cover the joint at this part.

According to Figs. 2 and 3, the twoy halves `of such a trough abut at their ends which carryy rings `13 adapted to interlock where they abutby means of a 'groove and feather and arev drawn together by bolts 15. vThe rings are firmly `bound to the concrete and reinforcementby means of lugs 14. Iron strips 16, rivetedl tothe bridge pieces 8 serve to further secure the bridge pieces 8 in the concrete wall, whilst iron strips 17 are doubled longitudinalreinforcements which with the lugs 14 tied in the-end wall by binding wire, form a metal-reinforced concrete skeleton structure. 20 is a steam pipe.

After tightening the brass bolts, asbestos cord soaked in red lead is .wound around the rings to fill the space between the two end walls of the trough sections and the remaining space is filled with plaster of Paris.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is j l. A trough for use in wet flax spinning comprising reinforced concrete trough sections arranged in longitudinal alinement each trough section being provided with end walls, conducting and coupling rings embedded in the opposed end walls of the trough sections and projecting beyond said walls and provided in their meeting faces with interconnecting means for closing the joint between them, and fastening members for uniting the opposed ends of the trough sections and holding the rings in coupled relation.

2. A trough for use in wet fiaX spinning comprising reinforced concrete trough sections arranged in longitudinal alinement, each trough section being provided with end walls, conducting and coupling rings embedded in the opposed end walls of the trough sections and projecting beyond said walls and provided in their meeting faces with interconnecting means for closing the joint between them, and fastening members for uniting the opposed ends of the trough sections and holding the rings in coupled relation, the rings being of a diameter less than the dimensions of the trough ends and forming cores about which filling material may be placed to close the gap between the trough ends.

3. A trough for use in wet flax spinning comprising reinforcedy concrete trough sections arranged, in longitudinal alinement, each trough section being provided with end walls, conducting and coupling rings embedded in the opposed end` walls of the trough sections and projecting beyond said walls and provided in their meeting faces `with interconnecting-means for closing the joint between them, said rings having lugs embedded in the end walls, and fastening bolts engaging lugs of the rings for uniting the ends of the trough sections and holding the rings in coupled relationship.

4. A trough for use in wet flax spinning comprising reinforced concrete trough sections arranged in longitudinal alinement,

each trough section being provided with end walls, conducting and coupling rings embedded in the opposed end walls of the trough sections and projecting'beyond said walls and provided Iin their meeting faces with yinterconnecting means `for closing the joint between them, said rings having lugs embedded in the opposed end Walls of the trough sections, reinforcing members in said walls of the trough sections and fastened to said lugs, and fastening bolts engaging certain of said lugs of the rings for uniting the opposed ends of the trough sections and holding the rings in assembled relationship.

5. A trough for use in wet flax spinning comprising reinforced concrete trough sections arranged in longitudinal alinement, each trough section being provided with end walls, conducting and coupling rings embedded in the opposed end walls of the trough sections and projecting beyond said walls and provided in their meeting faces with interconnecting means for closing the joint between them, said rings having lugs embedded in the end walls and being of less diameter than thedimensions of the walls and forming cores about which filling material may be placed to close the gap between the trough ends, andfastening bolts engaging lugs of the rings for uniting the trough ends and holding the rings in arsembled relationship. j

6. A trough for use in wet 'Hair spinning comprising concrete trough sections arranged in longitudinal alinement and each having longitudinal and transverse reinforcements and end walls, conducting and coupling rings connected to the longitudinal reinforcements and embedded in the opposed end walls of the trough sections and provided with lugs embedded therein, said rings having portions projecting beyond the end walls and provided with interconnecting means for closing the joints between them, reinforcing members embedded in said end Walls and connected to the lugs of the rings, and fastening bolts engaging lugs of the rings for uniting the trough ends and hold ing the rings in assembled relationship.
